BRACE FOR THRASHlNG-NIACHINES AND SEPARATORS.

SPECIFICATION forming part of Letters Patent No. 338,784, dated March 30, 1886.

Application filed October 12, 1885. Serial No. 179,660.

To all whom it may concern:

Be it known that I, JACKSON RITZMAN, a citizen of the United States, residing in Madison township, in the county of Butler and 5 State of Iowa, have invented certain new and useful Improvements in Braces for Threshing- Machines and Separators; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enx able others skilled in the art to which it appertains to make and use the same.

My invention relates to braces applied between the frames or housings and the wheels of thrashing-machines, whereby the wheels are 1 prevented from turning, and the machine is rendered stationary upon its wheels, whileit is operated by a suitable motor.

In the accompanying drawings, Figure l is a side elevation of a thrashing-machine and 2 separator having my invention applied to its front and rear wheels. Fig. 2 is a detail side View of the bottom frame and wheels of the said machine,provided with braces of modified construction. Fig. 3 is a section in the line 0000 of Fig. 1, and Fig. 4: is asection in the line y y of Fig. 2.

The letter A in the drawings designates the housing of a thrashing-machine and separator; B, its bottom frame; 0 G, the wheels,

and D the braces. A bar, (I, is firmly bolted at d to the bottom frame, B, or the housing A, its lower end being attached to the lower portion of the folly c of the wheel by means of a U shaped bolt, d, and nuts d The bolt (1 passes over the felly c and through the bar (I, so that when the nuts are drawn up tight it clamps the bar (1 against the felly, and thus prevents the wheel from turning on its axle.

0 The thrashing-machine and separator may be provided with one or more of the braces I)- one to each wheel, by preferenceand when checked by said braces from moving will retain its position steadily while being operated in the field or other place.

One of themost common modes of steadying such machines consists in driving pins or pegs into the ground and tying the wheels thereto. In using this mode, the wheels,hav-

(No model.)

ing asmall amount of freedom for rolling,soon 5o begin to rock,and jerk the pins or pegs loose,

so that the retaining mechanism requires to be watched constantly and readjusted at short intervals of time. All this care and labor is avoided with my invention, and the machine remains steady during its operation, no matter how long this may continue.

The bar (1, instead of being fastened to the lower portion of the wheel, may be fastened to the wheel above the axle, as shown in Fig. 3, and instead of being fastened to the folly it may be fastened to the spokes, as seen in Fig.

4. In the latter case a clamp-plate, al may be used instead of the U-shaped bolt d", and this clampplate would be provided with shoulders (1 fitted between the spokes c c, and the clamp-plate would by means of a bolt, e, be drawn tight upon the spokes, and thus the bar (I lirmly clamped thereto.

W'hichever of the described devices is employed for clamping or clipping the brace bar or bars (1 to the wheels,the bars will serve the purpose mentionedviz., steadying the machine while being operated.

NVhen the machine is not in use, the braces 7: can be rested on hooks, as at m in Fig. 2. Similar hooks will be provided on different parts of the framing or housing of the machine, according to the requirements of the different braces used.

I am awareof Letters Patent Nos. 187,607, 180,738, and 34,551, and make no claim for anything therein shown and claimed.

My invention differs from known contrivances, in that it provides a detachable longitudinal brace for connecting the wheel with the frame and preventing the rotation back and forth of the wheel, and also obviating such racking of the wheel as might be incident to the form of longitudinal brace which 0 merely connects the front and rear wheels on a side.

What I claim is- 1. The combination, with the frame A B and wheel 0, of the detachable longitudinal brace D, comprising bar d, pivot-bolt d, and the U- shaped clip-bolt d, having nuts d, substantially as and for the purpose described.

2. The combination, with frame A B and In testimony'whereof Iaflix my signaturein wheel 0, of the detachable longitudinal brace presence of two witnesses. D, comprising bar d, pivot-bolt d, and the connecting and clipping devices, substantially 5 as described, for firmly connecting the wheel Witnesses:

and brace, substantially as and for the pur- T. B. TAYLOR, pose set forth. H. B. WEEKS,
